  1. 故迂其途而誘之以利後人發先人至此知迂直之計者也

can be turned into actual advantage by celerity of movement.” Signal examples of this saying are afforded by the two famous passages across the Alps — that of Hannibal, which laid Italy at his mercy, and that of Napoleon two thousand years later, which resulted in the great victory of Marengo.

4. Thus, to take a long and circuitous route, after enticing the enemy out of the way, and though starting after him, to contrive to reach the goal before him, shows knowledge of the artifice of deviation.
